Abstract
The utility model discloses a locking device for a threaded moving block, which comprises a nut, wherein a groove is formed on an inner ring of the nut; a moving block is embedded in the groove; threads are formed on one surface of the moving block and matched with the inner ring of the nut; and a set screw is arranged on the other surface of the moving block and connected with the threads formed on the nut in a matching manner. The locking device is low in cost and can be used for locking the nut only by a moving block structure and the screw.
Description
Technical field
The utility model relates to locking device, specifically a kind of screw thread loose piece locking device.
Background technique
For prevent the axle fasten moving axially of nut, need lock it.Existing locking technology is mainly double nut and tight, and this locking mechanism is from effect and zero defect, but when the diameter of main shaft was big, the cost of nut own was higher, if still adopt also tight mode of aforementioned double nut, has strengthened the manufacture cost of part.
Summary of the invention
The utility model is studied and improved at the prior art above shortcomings, and a kind of screw thread loose piece locking device is provided, and is simple in structure, cost is low.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
The utility model comprises nut, and the nut inner ring has groove, and groove is embedded with loose piece, and the one side of loose piece is provided with screw thread and cooperates with the inner ring of described nut, and the another side of loose piece is provided with Cock screw, and the tapped through hole that is provided with on Cock screw and the described nut is connected.The Cock screw outside is tied with steel wire.
Technique effect of the present utility model is:
1, cost is low, only can realize locking to nut by loose piece structure and screw.
2, simple in structure, locking effect good, the tighten power of steel wire is received in the screw outside, has further strengthened locking effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model, broken section among the figure;
Fig. 2 is the right elevation of Fig. 1, broken section among the figure;
Fig. 3 is the enlarged view at A place among Fig. 1.
Embodiment
See Fig. 1, Fig. 2, the utility model comprises nut 1, the inner ring of nut 1 has groove, in loose piece 2 embeddings and the described groove, see Fig. 2, the bottom surface of loose piece 2 is provided with screw thread and cooperates the upper surface of loose piece 2 and nut 1 butt with the inner ring of nut 1, after promptly in loose piece 2 embeds described groove, nut 1 is as good as with complete nut in view of shape.See Fig. 3, the upper surface of loose piece 2 connects Cock screw 5, and tapped through hole 6 set on Cock screw 5 and the nut 1 is connected.
When the utility model used, nut 1 was threaded with main shaft 3 together with loose piece 2, when needs are fastening, screw Cock screw 5 and can fix loose piece 2, and then limited the trend that nut 1 rotatablely moves, and has realized the axial locking to nut 1.Simultaneously, steel wire 4 is tied up in the outer ring of nut 1 and through Cock screw 5, and its tighten power that Cock screw 5 is produced has further been consolidated the locking effect to nut 1.
Claims (2)
1. screw thread loose piece locking device, comprise nut, it is characterized in that described nut inner ring has groove, described groove is embedded with loose piece, the one side of described loose piece is provided with screw thread and cooperates with the inner ring of described nut, the another side of described loose piece is provided with Cock screw, and the tapped through hole that is provided with on described Cock screw and the described nut is connected.
2. screw thread loose piece locking device according to claim 1 is characterized in that the described Cock screw outside is tied with steel wire.
